REVOLVING FRUlT-EVAPORATOR.

SPECIFICATION forming part of Letters Patent N 0. 633,335, datedSeptember 19, 1899.

Application filed October 27, 1898. Serial No. 694,663. (No model.)

To all whom it may concern.-

Be it known that I, JAMEs W. CAMERON, a

citizen of the United States, and a resident of Evaporators, of whichthe following is a speci fication;

My invention consists of a rotary drier or evaporator in which isincorporated a wheel with a series of radial receptacles for trays forcontaining the substance to be treated, in conjunction with a blower,which is arranged laterally to the drying-wheel and the purpose of whichis to force air thereinto, and an attemperator for regulating the degreeof temperature of air supplied to the wheel.

In the accompanying drawings, Figure 1 represents a partial side viewand section of the apparatus with a portion of the tray-receptacleexposed. Fig. 2 represents a partial section and partial side view,looking at right angles to Fig. 1. Fig. 3 represents a vertical sectionthereof corresponding to Fig. 2 and including the .blower and theattemperator.

Fig. 4E represents a side view of the dryingwheel detached.

Similar letters of reference indicate similar parts.

The letter A indicates the shaft, on which is mounted the drying-wheel,which is composed, essentially, of two side heads B B and a surroundingdrum-head B, constituting a part of the wheel-casing, the side heads B Bbeing united by bracing-rods, as at B. Each of the side heads,furthermore, is provided on the interior portion thereof with grooveddisk O and a clamping-ring O, which form receptacles for the trays orpans in which in practice are placed fruits, flowers, or vegetables tobe treated, the grooves of said disks and clamping-rings being radial tothe axis of the drying-wheel. One of the pans is shown in end view at 5,Figs. 3 and 1.

Surrounding the drying-wheel is a'casing D, which in this example iseccentric thereto, and extending through one side of this casing is themouth E of the blower, which mouth is opposite to a circular range orseries of openings F on one side of the drying-wheel, which in themotion of the wheel are successively brought into communication withsaid mouth of the blower.

The blower is composed, essentially, of a casing G, a shaft G,concentric to the mouth or outlet of the blower, and a fan G, mounted onsaid shaft to operate in a well-known manner. The blower-casing G alsoincloses in its lower part a coil-pipe H, which constitutes theattemperator and may supply heat .or cold, as

may be expedient, to the air supplied to the apparatus by means of theblower, and the lower end of casing is immersed in a liquidbath, as ofwater, contained in the tank 1.

Access is had to the drying-wheel for the purpose of introducing andremoving the fruit-containing trays through an opening J next to thecircumference of the wheeland which is provided with a door J, as ismore clearly shown in Fig. 1, and for the purpose of imparting motion tothe drier-wheel shaft A has pulleys A A while for the purpose ofimparting motion to the blower-shaft it has a pulley G these pulleysbeing in practice connected with a proper source power.

Theoperation of the apparatus is as follows: The pans filled with thesubstance which itis desired to treat are introduced successivelythrough inlet-opening J of the frame into the proper receptacle of thedrying-wheel, and if desirable the pans may be held in position upon thewheel by means of a chain or the like wound thereon, or the Wheel may beprovided with a mechanical means, such as a catch, integral therewithfor that purpose. A

rotary motion is now imparted to the dryingwheel and to the blower-fan,with the efiect of presenting the fans successively to the ac tion ofthe blower through the opening F,

whereby the moisture is rapidly and effec- 9o radial receptacles adaptedto receive pans for containing the substances to be treated, awheel-surrounding casing eccentric to the axis of the wheel and providedwith an open- 3 facing of the heads, a surrounding casing eccentric tothe axis of the Wheel, provided with openings for the introduction andremoval of the pans to and from said receptacle and from the wheel, aspout leading from the lower part of the casing, a blower connected tothe casing at a point opposite the circular range of the openings of theperforated wheelhead and an attemperator connected with the blower, allsubstantially as and for the purpose herein described.

JAMES \V. CAMERON.
